I am using a standard BAPI, BAPI_SALESORDER_CREATEFROMDAT2. I extended two fileds in BAPIPARNR. And iam calling the standard BAPI and if sales order is created, then i need to update those fileds. Fileds are SORT2 in ADRC and AD_SMTPADR in ADC6. Is there any function module i can call to update the these tables using the customer number.
